UNITED STATES PATENT OFFIC GEARLES L. WILLIAMS, 0]? ALHAMBRA, CALIFORNIA, ASSIGNOR T0 THE WILTON WONDER BIL COMPANY LTD 01? ALHAMBRA, CALIFGREIA our; o om Rrrzn 4 Application t, rose. e85? I provide an oil riiie that is adapted for continuous operation by the use of one hand. Another ohject of the invention is to provide one hand oil rifle that will load itself automatically.

A. further object oi the invention is b0 pro vide one hand oil riile that will be under no pressure when not in use and hence that will remain loaded and always ready-tor use, without leakage.

A further oloject oil the invention is to pro ride a one hand oil riiie whose ilovv will. automatically cease when released from the hand.

A further object of the invention is to provide a one hand oil ride that is highly efiicient in operation and that is relatively cheap to so manu'lacture.

'l Vith these and other ohj cots in view reference is now had to the accompanying drawing in which Fig, 1 is a sectional elevation oi the oil lit rifle and container assembled and in the loaded position; and

2 is a sectional elevation of the oil rifle detached from the container and in the iinal position of discharge.

Having reference to the drawing like numerals refer to like parts throughout the several views, and the numeral 1 refers to a compression pump consisting of a cap 2, adapted to serve as the head of the pump,

which cap is designed for removable securement to a container, by threaded engagement therewith as illustrated in the drawing, or by any suitable method, the purpose of securement being more to obtain a'secure and rigid union of the pump with the container the usual manner such construction, and is in turn provided with centrally post tioned inlet ElllfiCQ 6. This lDlUCliI is also provided on itsnpper end with a concave or conical valve seat l in which is seated hall 8 or other valvetvherevvith to close the foot valve on the compression stroke oi the plunger 9, to open the said valve on the suction strolre.

@perahly mounted in the said harrel 3; is the said plunger comprising a suction block 10, out similar construction to that of the lolock 5 of the said valve r, except to size, and this suction hloclr contains outlet orifice i1 terminating in a seat 1%, and is also provided with a hall 13 mounted in this seat to complete the said suction valve, and is adapted to threadedly engage the lower end of a hollow plunger rod, as shown,

and mounted therein for a purpose to he ea= plained.

Shaped around this last named hl cl: is a cup leather it or the usual type and for the usual purpose, and that part oi? the barrel through which the plunger moves during operation will he termcd'the oil chamber 15,

perpendicular to the plunger rod 16 and or ranged with the plunger rod for rotation about the axis of the harrel.

and a plunger rod 16 is provided to operate The nozzle pine 19 obviously is also hollow this passageway and by that there can be no discharge through the hollow plunger rod, and further that upon this chamber being loaded with the plunger brought to the above mentioned position there will simultaneously be caused a cessation of flow through said nozzle.

It is now plainly evident that to discharge the contents of the oil chamber through the nozzle a compression stroke will be required and to provide this compression stroke a handle 25 is provided that forms a part of the elbow fitting 18, and this handle is positioned extended in a direction opposite to and in prolongation of the nozzle ipe 19, and a palr of oppositely extended grips 26 and 27 respectively are attached to or formed integral with the said cap 2 where they are positioned in cooperable relation with said handle whereby the compression stroke may be tprovided by resting that part of the palm o the hand, at the base of the thumb, upon the top of the said handle, with the thumb and first finger astride the elbow fitting, and with the first finger gripping the smaller or shorter grip 26 and the three remaining fingers comfortably engaging the longer grip 27 ,whereby, upon closing the hand with a gripping movement, the handle will be moved downward to the grips forcing the content of the pump out of the nozzle, the relative position of the handle with respect to the grips being rotated to a slight angle of diversion (not shown) from one another to comfortably fit the hand automatically, as the device is seized for operation, by the slight unhindered rotation of the plunger rod in the cap.

Upon the compression stroke occurrin the foot valve will close automatically an the suction valve will open in the general manner shown in Fig. 2, and to prevent the ball of this valve from lodging in the nozzle pipe a light spring, represented as at 28, is placed in the passageway of the plunger rod and above the ball whereby should the device be turned upside down the said spring would fall to the point of change of direction in said passageway, within the elbow fitting, there to rest without obstructing flow through its diametrical dimensions being less than that of the ball, preventing the ball from entering this pipe.

By this'means operation may occur with the device in any position. a

As the device depends for operation upon bringing the handle and grip together by the gripping of one hand it is obviously necessary that the handle and grip be spaced a proper distance apart normally to be conveniently seized by one hand, and as the barrel length is in excess of this normal distance between the handle and grip, means is provided to prevent the spring 24 from raising the plunger rod and its attendant handle beyond this distance, which means to prevent this extreme action consists of a gauge 29 provided to determine the length of compression stroke, whereb to accommodate the average hand in gripplng, and which gauge consists of a tubular member loosely surrounding said plunger rod in said barrel and cut to the proper length that one end will bear against the plunger, with the opposite end thereof bearing against the head of the cap, at the end of the suction stroke, the gauge being free to move with the plunger and plunger god on the compression stroke of these memers.

By this means and by cutting this gauge to the required length it is obvious that the handle and grips of the device will always be in a position for convenient seizure for operation.

In use the container Wlll be filled in the usual manner with the proper contents when 26 and 27 acting as a wrench-lever therefor.

Should the level of the content be above the plunger the content will gradually fill the oil chamber without external assistance, but in operation pressure upon the said handle 25 will be used to force the plunger downward, compressin the spring 24 in the oil chamber and disp acing the air therein, thus forcing it upward through the hollow piston rod passagewa and out through the nozzle, the foot valve eing closed by the act of displacement.

Upon loosening the grip upon the handle and grip members the sprmg will yieldingly move the plunger upward and provide a suction stroke which, by creating a partial vacuum in the oil chamber, will draw the content into this chamber loading it for subsequent use.

Now by closing the hand with a gripping action the handle will be forced downward and toward the cap, which movement will force the plunger rod and plunger to a like movement, when the content of the oil chamber will be forced upward through the passageway, and past the suction valve for forced expulsion of the content through the fine jet orifice of the nozzle to its destination.

It is understood that oil rifles for a like purpose have been devised however, the herein described rifle is self loading as the suction stroke is automatically obtained in the manner before described, and being self load- III Ill

ing is ever-loaded and ready for operation as an obvious result of the self loading, and by means of the gauge is self gauging, and is further self stopping, and also as the device is under zero pressure when not in use there is positively no danger of leakage with its consequent waste, and during 0 eration and withthe pressure confined against the foot valve on the one hand and the nozzle on the other it is obvious that an leakage occurring can only be through a lea y foot valve when its content might possibly drain back into the container without loss.

To prevent sediment entering the oil chamher to lodge under the ball of the foot valve, or to choke the screen of the said nozzle, a screen may be added to the foot valve as shown at 30, and should the plunger become worn that the content of the chamber may pass thereby during the compression stroke, the usual relief vent 31 is provided in the barrel and positioned to discharge into the container. 1 1

Heretofore the duration of continuous application of the jet of oil has been comparatively brief requiring several operations of the plun er to completely oil, say one entire spring 0 an automobile, and with each operation it is a known fact that much loss will occur between the time the 1' et leaves the rifle until it is finally brought into contact with its target. This is due to the fact of the comparatively small available power found in a single digit of a hand, which power in turn is the'determining factor fort-he size of the plunger, and the, oil chamber forming its cylinder.

Obviously then a device adapted to utilize the comparatively and acknowledged greater power of a grip may also provide an oil chamber of relatively greater capacity which,

by one stroke of the plunger will completely Oil the spring with correspondingly less loss of oil in the one stroke than in the many, and with greater force.
